KVERT reported that on 15 June an ash plume from Ebeko was visible in satellite images drifting 14 km SE. Video data from SVERT and KBGS RAS (Kamchatka Branch, Geophysical Service, Russian Academy of Sciences) showed ash explosions during 17-18 June that sent ash plumes to 2.5-3 km (8,200-10,000 ft) a.s.l. The Aviation Color Code remained at Orange (the second highest level on a four-color scale).

Geologic Background. The flat-topped summit of the central cone of Ebeko volcano, one of the most active in the Kuril Islands, occupies the northern end of Paramushir Island. Three summit craters located along a SSW-NNE line form Ebeko volcano proper, at the northern end of a complex of five volcanic cones. Blocky lava flows extend west from Ebeko and SE from the neighboring Nezametnyi cone. The eastern part of the southern crater contains strong solfataras and a large boiling spring. The central crater is filled by a lake about 20 m deep whose shores are lined with steaming solfataras; the northern crater lies across a narrow, low barrier from the central crater and contains a small, cold crescentic lake. Historical activity, recorded since the late-18th century, has been restricted to small-to-moderate explosive eruptions from the summit craters. Intense fumarolic activity occurs in the summit craters, on the outer flanks of the cone, and in lateral explosion craters.
